Disturbances are NOT better explained by a preexisting, established or evolving neurocognitive disorder and do NOT occur in the context of a severely reduced level of arousal such as coma E. There is evidence from the history and physical exam and/or labs that the disturbance is caused by a medical condition, substance intoxication or withdrawal, or medication/toxin side effect American Psychiatric Association.

6 Delirium Coma: defined by level of arousal SAS 1 or 2, RASS = -4 or -5. Only responsive to physical or noxious stimulus, if at all Unable to communicate Comatose patients should be reassessed over time to permit delirium scoring Scoring is optimal during a patient's maximal level of wakefulness Eligible for delirium when they arouse to verbal stimulus RASS -3: brief eye opening to voice, no contact SAS 3: awakens to verbal stimulus, but drifts off Confusion Assessment Method (CAM, CAM-ICU).

9 Electrolyte imbalance Visual/hearing deficits Sleep deprivation Limits of Evidence: Delirium Prevention Perform early mobilization of adult ICU patients whenever feasible to reduce the incidence and duration of delirium (+1B). No recommendation for Using pharmacologic delirium prevention protocol Using combined nonpharmacologic and pharmacologic delirium prevention protocol as no compelling data demonstrate that these reduce the incidence or duration of delirium (0,C). We do not suggest that either haloperidol or atypical antipsychotics be administered to prevent delirium in adult ICU. patients (-2C). We provide no recommendation for the use of dexmedetomidine to prevent delirium in adult ICU patients, as there is no compelling evidence regarding its effectiveness in these patients (O,C).
